Karma literally means "deed or act," but more broadly describes the principle of cause and effect. Simply stated, karma is the law of action and reaction which governs consciousness. This includes family, community, nation, race and religion, even planetary group karma. So if we, individually or collectively, unconditionally love and give, we will be loved and given to. The individuals or groups who act soulfully or maliciously toward us are the vehicle of our own karmic creation. The people who manifest your karma are also living through past karma and simultaneously creating future karma. Imagine how intricately interconnected all the cycles of karma are for our planet's life forms. Hinduastrology, or Jyotisha, details a real relation between ourselves and the geography of the solar system and certain star clusters, but it is not a cause-effect relation. Planets and stars don't cause or dictate karma. Their orbital relationships establish proper conditions for karmas to activate and a particular type of personality nature to develop. Jyotisha describes a relation of revealment: it reveals prarabdha karmic patterns for a given birth and how we will generally react to them (kriyamana karma).
